Sanitary Sewer Smoke Testing Overview
Excess rainwater and groundwater entering the sewer system increases operational costs and can potentially cause expensive sanitary sewer backups. GRU wastewater collection crews will be smoke testing the sanitary sewer lines in your neighborhood to identify areas of concern in the collection system.
What you will need to do:
• Prepare ALL drains (such as floor drains, garage sinks, etc.) prior to smoke testing
• Fill drains with water by:
o Running the faucet for 60 seconds
o Filling the drain with approx. 3 cups of water
*Any person with respiratory conditions such as emphysema or asthma should avoid exposure to the smoke. The smoke should not enter the building but can if plumbing drains are dry or if piping in or under the house is defective. If smoke enters the building, any person with respiratory conditions should leave the home for the duration of the test and notify nearby GRU crews.
